CHashSet<T>

CHashSet<T> is a generic class that implements the ISet<T> interface.

Description

The CHashSet<T> class is an implementation of the unordered dynamic data set of type T, with the required uniqueness of each value. This class provides basic methods to work with sets and related operations, such as: the union and intersection of sets, definition of strict and non-strict subsets, and others.

Declaration

class CHashSet : public ISet<T>

Class Methods

Method	Description
Add	Adds an element to a set
Count	Returns the number of elements in a set
Comparer	Determines whether a set contains an element with the specified value
Contains	Returns a pointer to the IEqualityComparer<T> interface, used to organize a set
TrimExcess	Sets the capacity of a set to the actual number of elements, and thus frees up unused memory
CopyTo	Copies all elements of a set to the specified array starting at the specified index
Clear	Removes all elements from a set
Remove	Removes the specified element from a set
ExceptWith	Produces the operation of difference between the current collection and a passed collection (array)
IntersectWith	Produces the operation of intersection of the current collection and a passed collection (array)
SymmetricExceptWith	Produces the operation of symmetrical difference between the current collection and a passed collection (array)
UnionWith	Produces the union of the current collection and a passed collection (array)
IsProperSubsetOf	Determines whether the current set is a proper subset of the specified collection or array
IsProperSupersetOf	Determines whether the current set is a proper superset of the specified collection or array
IsSubsetOf	Determines whether the current set is a subset of the specified collection or array
IsSupersetOf	Determines whether the current set is a superset of the specified collection or array
Overlaps	Determines whether the current set overlaps the specified collection or array
SetEquals	Determines whether the current set contains all elements of the specified collection or array
